Mercury Glass Rose Flower Feather Tree Christmas Ornaments

Four rare tiny rose or flower shape mercury silvered glass Christmas ornaments from the 1920s or 1930s, just over 3/4 of an inch diameter - feather tree size (I've shown a quarter in the first photo for scale). The pike openings are at the center backs, button style. The ornaments have a transparent overwash orange tinted coloring, which may have been red originally. They're in excellent condition with no breaks or damage. I suspect they were originally attached to wire or chenille stems and were later converted to Christmas ornaments. Attach to your tree branches with wire to better show the flower sides.
